Italian island no patients with coronavirus has scientists baffled

On the Italian island of Giglio, none of the residents is not affected by the coronavirus. However, even with this zero indicator the only doctor of the island was still concerned about the outbreak COVID-19. Mysterious example of Giglio begs many questions. Could the locals really be infected, but they do not show symptoms? Or secret resistance to the virus lies in the genetic characteristics of the islanders? Maybe they just got lucky?

Итальянский остров без больных коронавирусом поставил ученых в тупик

None of the approximately 800 inhabitants of the island of Giglio reported that they developed symptoms COVID-19, although the conditions apparently favored spread of the disease like wildfire, the Associated Press reports.

Dr. Armando Schiaffino, the only doctor of the island for 40 years, shares the concern about a potential local outbreak.

“Every time there is a normal childhood disease such as scarlet fever, measles or chicken pox, a few days almost all infected,” says doctor.

Researcher in breast cancer at the University of Milan where she works as a Professor of epidemiology, Paola Muti decided to try to figure out why this has not happened this time.

“Dr. Schiaffino came up to me and said, “Hey, look, Paula, this is incredible. In this pandemic, with all the incidents that happened on the island, no one is sick.” So I said to myself: “Well, because we may be here for research, right? I’m here,” says Paola Muti.

By the time Turbidity was due to taken in Italy the strict rules of localization in “trapped” on the island. That it was especially puzzled is the fact that many islanders have had close contact with visitors.

The first known case of the disease COVID-19 on Giglio have been reported in men aged 60 years, who arrived on the island on February 18 for a couple of days before the first “indigenous case” in Italy were diagnosed in the North of the country. According to Muti, this man came to Giglio for the funeral of a relative, and “all the time coughing”. And as you know, the virus is mainly spread through droplets when someone coughs, sneezes or talks. The sick man was back on the ferry the same day to the mainland and died three weeks later in the hospital.

March 5, four days before it was declared a national quarantine, even three visitors arrived from the mainland and on the island gave a positive result for coronavirus. One of them was a German from Northern Italy, which became the original epicenter of the outbreak in Europe. Some days he spoke to friends from Giglio, including in public eateries. After a week due to severe coughing he was examined on the island, and the result was positive. It isolated itself in the house on Giglio.

There were other known cases, including islanders who lived in Australia for two years, and then in mid-March, returned to Giglio during a lockdown, to see her parents. According to Muti, three days after arriving on Giglio, he developed mild fever He isolated themselves in the house of his parents.

On Giglio there was not a single other occasion, including the time of unlock at the beginning of June and the arrival of tourists from all over Italy.

Tuscan office of health quickly sent to the island of Giglio kits to test for antibodies to see if there were any residents diseases COVID-19. At the end of April the inhabitants of the island had to take a blood test lined up near the school and the doctor’s office on the island.

Of the 800 or so year-round residents of the island 723 volunteered to be tested.

Paola Muti says that only one Islander was discovered antibodies have an elderly local resident who sailed on the ferry to the island with a German guest said Muti.

Intrigued by why “the virus apparently did not interact” with the indigenous population of the island, Muti has not made any conclusions by the time I was preparing to leave the island this month. She said she plans to record their research for eventual publication.

Perhaps Muti suggested that the islanders were not exposed to a sufficient number of coronavirus infection to get infected.

This opportunity was announced by the head of the division of infectious diseases at the Rome hospital Tor Vergata Massimo Andreoni, noting that some patients are simply less capable of spreading disease for reasons that are still not clear.
